I guess I just don’t think that sounds like a very safe/secure way to manage operational security concerns, especially when there is this much at stake. Consider DANE’s already_ large usage footprint. Those systems’ security will suffer from a compromise here too. This isn’t all gloom and doom. Rigorous discussions and publications about on-path/off-path/topology/etc. considerations do exist (even in the context of DNSSEC). I just really think that before we get too far down the road of rolling, then rolling again, then rolling again, we would be well served by considering the needs for resilient/secure key learning for our global Root.

Fair point, those were my words (not trying to impute them to you), and if I missed your point: I’m doubly sorry. I was just saying that there are a lot of ways this can bite us, and if we don’t make it clear how important Root KSK mgmt is, and what the height requirements are, we might pay for that later.
